QoS Commands

auto qos classify

To automatically configure quality of service (QoS) classification for untrusted devices within a QoS domain, use the auto qos classify command in interface configuration mode. To return to the default setting, use the no form of this command.

auto qos classify [police]

no auto qos classify [police]

Syntax Description

police

(Optional) Configure QoS policing for untrusted devices.

Command Default

Auto-QoS classify is disabled on the port.

Cisco IOS XE Everest 16.5.1a

This command was introduced.

Usage Guidelines

Use this command to configure the QoS for trusted interfaces within the QoS domain. The QoS domain includes the device, the network interior, and edge devices that can classify incoming traffic for QoS.

When auto-QoS is enabled, it uses the ingress packet label to categorize traffic, to assign packet labels, and to configure the ingress and egress queues.

Auto-QoS configures the device for connectivity with a trusted interface. The QoS labels of incoming packets are trusted. For nonrouted ports, the CoS value of the incoming packets is trusted. For routed ports, the DSCP value of the incoming packet is trusted.

To take advantage of the auto-QoS defaults, you should enable auto-QoS before you configure other QoS commands. You can fine-tune the auto-QoS configuration after you enable auto-QoS.


Note

The device applies the auto-QoS-generated commands as if the commands were entered from the command-line interface (CLI). An existing user configuration can cause the application of the generated commands to fail or to be overridden by the generated commands. These actions occur without warning. If all the generated commands are successfully applied, any user-entered configuration that was not overridden remains in the running configuration. Any user-entered configuration that was overridden can be retrieved by reloading the device without saving the current configuration to memory. If the generated commands fail to be applied, the previous running configuration is restored.

After auto-QoS is enabled, do not modify a policy map or aggregate policer that includes AutoQoS in its name. If you need to modify the policy map or aggregate policer, make a copy of it, and change the copied policy map or policer. To use the new policy map instead of the generated one, remove the generated policy map from the interface, and apply the new policy map.

To display the QoS configuration that is automatically generated when auto-QoS is enabled, enable debugging before you enable auto-QoS. Use the debug auto qos privileged EXEC command to enable auto-QoS debugging.

The following policy maps and class maps are created and applied when running the auto qos classify and auto qos classify police commands:

Policy maps (For the auto qos classify police command):

  • AutoQos-4.0-Classify-Police-Input-Policy

  • AutoQos-4.0-Output-Policy

Class maps:

  • AutoQos-4.0-Multimedia-Conf-Class (match-any)

  • AutoQos-4.0-Output-Scavenger-Queue (match-any)

  • AutoQos-4.0-Output-Multimedia-Strm-Queue (match-any)

To disable auto-QoS on a port, use the no auto qos classify interface configuration command. Only the auto-QoS-generated interface configuration commands for this port are removed. If this is the last port on which auto-QoS is enabled and you enter the no auto qos classify command, auto-QoS is considered disabled even though the auto-QoS-generated global configuration commands remain (to avoid disrupting traffic on other ports affected by the global configuration).

Examples

This example shows how to enable auto-QoS classification of an untrusted device and police traffic:

You can verify your settings by entering the show auto qos interface interface-id privileged EXEC command.

auto qos trust

To automatically configure quality of service (QoS) for trusted interfaces within a QoS domain, use the auto qos trust command in interface configuration mode. To return to the default setting, use the no form of this command.

auto qos trust {cos | dscp}

no auto qos trust {cos | dscp}

Syntax Description

cos

Trusts the CoS packet classification.

dscp

Trusts the DSCP packet classification.

Command Default

Auto-QoS trust is disabled on the port.

This command was introduced.

Usage Guidelines

Use this command to configure the QoS appropriate for video traffic within the QoS domain. The QoS domain includes the device, the network interior, and edge devices that can classify incoming traffic for QoS. When auto-QoS is enabled, it uses the ingress packet label to categorize traffic, to assign packet labels, and to configure the ingress and egress queues. For more information, see the queue tables at the end of this section.

Auto-QoS configures the device for video connectivity to a Cisco TelePresence system, a Cisco IP camera, or a Cisco digital media player.

To take advantage of the auto-QoS defaults, you should enable auto-QoS before you configure other QoS commands. You can fine-tune the auto-QoS configuration after you enable auto-QoS.

The device applies the auto-QoS-generated commands as if the commands were entered from the command-line interface (CLI). An existing user configuration can cause the application of the generated commands to fail or to be overridden by the generated commands. These actions occur without warning. If all the generated commands are successfully applied, any user-entered configuration that was not overridden remains in the running configuration. Any user-entered configuration that was overridden can be retrieved by reloading the device without saving the current configuration to memory. If the generated commands fail to be applied, the previous running configuration is restored.

If this is the first port on which you have enabled auto-QoS, the auto-QoS-generated global configuration commands are executed followed by the interface configuration commands. If you enable auto-QoS on another port, only the auto-QoS-generated interface configuration commands for that port are executed.

After auto-QoS is enabled, do not modify a policy map or aggregate policer that includes AutoQoS in its name. If you need to modify the policy map or aggregate policer, make a copy of it, and change the copied policy map or policer. To use the new policy map instead of the generated one, remove the generated policy map from the interface, and apply the new policy map.

To display the QoS configuration that is automatically generated when auto-QoS is enabled, enable debugging before you enable auto-QoS. Use the debug auto qos privileged EXEC command to enable auto-QoS debugging.

  • AutoQos-4.0-Output-Scavenger-Queue (match-any)

  • AutoQos-4.0-Output-Multimedia-Strm-Queue (match-any)

To disable auto-QoS on a port, use the no auto qos video interface configuration command. Only the auto-QoS-generated interface configuration commands for this port are removed. If this is the last port on which auto-QoS is enabled, and you enter the no auto qos video command, auto-QoS is considered disabled even though the auto-QoS-generated global configuration commands remain (to avoid disrupting traffic on other ports affected by the global configuration).

You can verify your settings by entering the show auto qos video interface interface-id privileged EXEC command.

auto qos voip

To automatically configure quality of service (QoS) for voice over IP (VoIP) within a QoS domain, use the auto qos voip command in interface configuration mode. Use the no form of this command to return to the default setting.

auto qos voip { cisco-phone | cisco-softphone | trust}

no auto qos voip { cisco-phone | cisco-softphone | trust}

Syntax Description

cisco-phone

Specifies a port connected to a Cisco IP phone, and automatically configures QoS for VoIP. The QoS labels of incoming packets are trusted only when the telephone is detected.

cisco-softphone

Specifies a port connected to a device running the Cisco SoftPhone, and automatically configures QoS for VoIP.

trust

Specifies a port connected to a trusted device, and automatically configures QoS for VoIP. The QoS labels of incoming packets are trusted. For nonrouted ports, the CoS value of the incoming packet is trusted. For routed ports, the DSCP value of the incoming packet is trusted.

Command Default

Auto-QoS is disabled on the port.

When auto-QoS is enabled, it uses the ingress packet label to categorize traffic, to assign packet labels, and to configure the ingress and egress queues.

Command Default

Interface configuration

Command History

Release

Modification

Cisco IOS XE Everest 16.5.1a

This command was introduced.

Usage Guidelines

Use this command to configure the QoS appropriate for VoIP traffic within the QoS domain. The QoS domain includes the device, the network interior, and edge devices that can classify incoming traffic for QoS.

Auto-QoS configures the device for VoIP with Cisco IP phones on device and routed ports and for devices running the Cisco SoftPhone application. These releases support only Cisco IP SoftPhone Version 1.3(3) or later. Connected devices must use Cisco Call Manager Version 4 or later.

To take advantage of the auto-QoS defaults, you should enable auto-QoS before you configure other QoS commands. You can fine-tune the auto-QoS configuration after you enable auto-QoS.


Note

The device applies the auto-QoS-generated commands as if the commands were entered from the command-line interface (CLI). An existing user configuration can cause the application of the generated commands to fail or to be overridden by the generated commands. These actions occur without warning. If all the generated commands are successfully applied, any user-entered configuration that was not overridden remains in the running configuration. Any user-entered configuration that was overridden can be retrieved by reloading the device without saving the current configuration to memory. If the generated commands fail to be applied, the previous running configuration is restored.

If this is the first port on which you have enabled auto-QoS, the auto-QoS-generated global configuration commands are executed followed by the interface configuration commands. If you enable auto-QoS on another port, only the auto-QoS-generated interface configuration commands for that port are executed.

When you enter the auto qos voip cisco-phone interface configuration command on a port at the edge of the network that is connected to a Cisco IP phone, the device enables the trusted boundary feature. The device uses the Cisco Discovery Protocol (CDP) to detect the presence of a Cisco IP phone. When a Cisco IP phone is detected, the ingress classification on the port is set to trust the QoS label received in the packet. The device also uses policing to determine whether a packet is in or out of profile and to specify the action on the packet. If the packet does not have a DSCP value of 24, 26, or 46 or is out of profile, the device changes the DSCP value to 0. When a Cisco IP phone is absent, the ingress classification is set to not trust the QoS label in the packet. The policing is applied to those traffic matching the policy-map classification before the device enables the trust boundary feature.

  • When you enter the auto qos voip cisco-softphone interface configuration command on a port at the edge of the network that is connected to a device running the Cisco SoftPhone, the device uses policing to decide whether a packet is in or out of profile and to specify the action on the packet. If the packet does not have a DSCP value of 24, 26, or 46 or is out of profile, the device changes the DSCP value to 0.
  • When you enter the auto qos voip trust interface configuration command on a port connected to the network interior, the device trusts the CoS value for nonrouted ports or the DSCP value for routed ports in ingress packets (the assumption is that traffic has already been classified by other edge devices).

You can enable auto-QoS on static, dynamic-access, and voice VLAN access, and trunk ports. When enabling auto-QoS with a Cisco IP phone on a routed port, you must assign a static IP address to the IP phone.


Note

When a device running Cisco SoftPhone is connected to a device or routed port, the device supports only one Cisco SoftPhone application per port.

After auto-QoS is enabled, do not modify a policy map or aggregate policer that includes AutoQoS in its name. If you need to modify the policy map or aggregate policer, make a copy of it, and change the copied policy map or policer. To use the new policy map instead of the generated one, remove the generated policy map from the interface, and apply the new policy map.

To display the QoS configuration that is automatically generated when auto-QoS is enabled, enable debugging before you enable auto-QoS. Use the debug auto qos privileged EXEC command to enable auto-QoS debugging.

  • class AutoQos-4.0-Voip-Signal-CiscoPhone-Class

  • class AutoQos-4.0-Default-Class

To disable auto-QoS on a port, use the no auto qos voip interface configuration command. Only the auto-QoS-generated interface configuration commands for this port are removed. If this is the last port on which auto-QoS is enabled and you enter the no auto qos voip command, auto-QoS is considered disabled even though the auto-QoS-generated global configuration commands remain (to avoid disrupting traffic on other ports affected by the global configuration).

The device configures egress queues on the port according to the settings in this table.

Cisco IOS XE Everest 16.5.1a

This command was introduced.

Usage Guidelines

Before using the class command, you must use the policy-map global configuration command to identify the policy map and enter policy-map configuration mode. After specifying a policy map, you can configure a policy for new classes or modify a policy for any existing classes in that policy map. You attach the policy map to a port by using the service-policy interface configuration command.

After entering the class command, you enter the policy-map class configuration mode. These configuration commands are available:

  • admit —Admits a request for Call Admission Control (CAC)

  • bandwidth —Specifies the bandwidth allocated to the class.

  • exit —Exits the policy-map class configuration mode and returns to policy-map configuration mode.

  • no —Returns a command to its default setting.

  • police —Defines a policer or aggregate policer for the classified traffic. The policer specifies the bandwidth limitations and the action to take when the limits are exceeded. For more information about this command, see Cisco IOS Quality of Service Solutions Command Reference available on Cisco.com.

  • priority —Assigns scheduling priority to a class of traffic belonging to a policy map.

  • queue-buffers —Configures the queue buffer for the class.

  • queue-limit —Specifies the maximum number of packets the queue can hold for a class policy configured in a policy map.

  • service-policy —Configures a QoS service policy.

  • set —Specifies a value to be assigned to the classified traffic. For more information, see the set command.

  • shape —Specifies average or peak rate traffic shaping. For more information about this command, see Cisco IOS Quality of Service Solutions Command Reference available on Cisco.com.

To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode, use the end command.

The class command performs the same function as the class-map global configuration command. Use the class command when a new classification, which is not shared with any other ports, is needed. Use the class-map command when the map is shared among many ports.

You can configure a default class by using the class class-default policy-map configuration command. Unclassified traffic (traffic that does not meet the match criteria specified in the traffic classes) is treated as default traffic.

You can verify your settings by entering the show policy-map privileged EXEC command.

Examples

This example shows how to create a policy map called policy1. When attached to the ingress direction, it matches all the incoming traffic defined in class1 and polices the traffic at an average rate of 1 Mb/s and bursts at 1000 bytes, marking down exceeding traffic via a table-map. 

Device(config)# policy-map policy1
Device(config-pmap)# class class1
Device(config-pmap-c)# police cir 1000000 bc 1000 conform-action 
transmit exceed-action set-dscp-transmit dscp table EXEC_TABLE
Device(config-pmap-c)# exit

This example shows how to configure a default traffic class to a policy map. It also shows how the default traffic class is automatically placed at the end of policy-map pm3 even though class-default was configured first: 

Device# configure terminal 
Device(config)# class-map cm-3
Device(config-cmap)# match ip dscp 30
Device(config-cmap)# exit

Device(config)# class-map cm-4
Device(config-cmap)# match ip dscp 40
Device(config-cmap)# exit

Device(config)# policy-map pm3
Device(config-pmap)# class class-default
Device(config-pmap-c)# set dscp 10
Device(config-pmap-c)# exit

Device(config-pmap)# class cm-3
Device(config-pmap-c)# set dscp 4
Device(config-pmap-c)# exit

Device(config-pmap)# class cm-4
Device(config-pmap-c)# set precedence 5
Device(config-pmap-c)# exit
Device(config-pmap)# exit

Device# show policy-map pm3
Policy Map pm3
  Class cm-3
    set dscp 4
  Class cm-4
    set precedence 5
  Class class-default
    set dscp af11

class-map

To create a class map to be used for matching packets to the class whose name you specify and to enter class-map configuration mode, use the class-map command in global configuration mode. Use the no form of this command to delete an existing class map and to return to global or policy map configuration mode.

class-map class-map name { match-any | match-all}

no class-map class-map name { match-any | match-all}

Syntax Description

match-any

(Optional) Perform a logical-OR of the matching statements under this class map. One or more criteria must be matched.

match-all

(Optional) Performs a logical-AND of the matching statements under this class map. All criterias must match.

class-map-name

The class map name.

Command Default

No class maps are defined.

Command Modes

Global configuration

Release

Modification

Cisco IOS XE Everest 16.5.1a

This command was introduced.

Usage Guidelines

Use this command to specify the name of the class for which you want to create or modify class-map match criteria and to enter class-map configuration mode.

The class-map command and its subcommands are used to define packet classification, marking, and aggregate policing as part of a globally named service policy applied on a per-port basis.

After you are in quality of service (QoS) class-map configuration mode, these configuration commands are available:

  • description—Describes the class map (up to 200 characters). The show class-map privileged EXEC command displays the description and the name of the class map.

  • exit—Exits from QoS class-map configuration mode.

  • match—Configures classification criteria.

  • no—Removes a match statement from a class map.

If you enter the match-any keyword, you can only use it to specify an extended named access control list (ACL) with the match access-group class-map configuration command.

To define packet classification on a physical-port basis, only one match command per class map is supported.

The ACL can have multiple access control entries (ACEs).


Note

You cannot configure IPv4 and IPv6 classification criteria simultaneously in the same class-map. However, they can be configured in different class-maps in the same policy.

Examples

This example shows how to configure the class map called class1 with one match criterion, which is an access list called 103: 


Device(config)# access-list 103 permit ip any any dscp 10
Device(config)# class-map class1
Device(config-cmap)# match access-group 103
Device(config-cmap)# exit

This example shows how to delete the class map class1: 

Device(config)# no class-map class1

You can verify your settings by entering the show class-map privileged EXEC command.

debug auto qos

To enable debugging of the automatic quality of service (auto-QoS) feature, use the debug auto qos command in privileged EXEC mode. Use the no form of this command to disable debugging.

debug auto qos

no debug auto qos

Syntax Description

This command has no arguments or keywords.

Command Default

Auto-QoS debugging is disabled.

Command Modes

Privileged EXEC

Command History

Release

Modification

Cisco IOS XE Everest 16.5.1a

This command was introduced.

Usage Guidelines

To display the QoS configuration that is automatically generated when auto-QoS is enabled, enable debugging before you enable auto-QoS. You enable debugging by entering the debug auto qos privileged EXEC command.

The undebug auto qos command is the same as the no debug auto qos command.

When you enable debugging on a device stack, it is enabled only on the active device. To enable debugging on a stack member, you can start a session from the active device by using the session switch-number privileged EXEC command. Then enter the debug command at the command-line prompt of the stack member. You also can use the remote command stack-member-number LINE privileged EXEC command on the active device to enable debugging on a member device without first starting a session.

Examples

This example shows how to display the QoS configuration that is automatically generated when auto-QoS is enabled:


Device# debug auto qos
AutoQoS debugging is on
Device# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Device(config)# interface hundredgigabitethernet 1/0/3
Device(config-if)# auto qos voip cisco-phone

match (class-map configuration)

To define the match criteria to classify traffic, use the match command in class-map configuration mode. Use the no form of this command to remove the match criteria.

Modification

Cisco IOS XE Everest 16.5.1a

This command was introduced.

Cisco IOS XE Everest 16.6.1

The class-map class-map-name keyword is removed.

The mpls experimental-value , non-client-nrt , protocol protocol-name , and wlan wlan-id keywords are added.

Usage Guidelines

The match command is used to specify which fields in the incoming packets are examined to classify the packets. Only the IP access group or the MAC access group matching to the Ether Type/Len are supported.

If you enter the class-map match-anyclass-map-name global configuration command, you can enter the following match commands:

  • match access-group name acl-name


    Note

    The ACL must be an extended named ACL.

    This is not applicable to Cisco Catalyst 9500 Series High Performance Switches.

  • match ip dscp dscp-list

  • match ip precedence ip-precedence-list

The match access-group acl-index command is not supported.

To define packet classification on a physical-port basis, only one match command per class map is supported. In this situation, the match-any keyword is equivalent.

For the match ip dscp dscp-list or the match ip precedence ip-precedence-list command, you can enter a mnemonic name for a commonly used value. For example, you can enter the match ip dscp af11 command, which is the same as entering the match ip dscp 10 command. You can enter the match ip precedence critical command, which is the same as entering the match ip precedence 5 command. For a list of supported mnemonics, enter the match ip dscp ? or the match ip precedence ? command to see the command-line help strings.

Use the input-interface interface-id-list keyword when you are configuring an interface-level class map in a hierarchical policy map. For the interface-id-list , you can specify up to six entries.

Examples

This example shows how to create a class map called class2, which matches all the incoming traffic with DSCP values of 10, 11, and 12: 

Device(config)# class-map class2
Device(config-cmap)# match ip dscp 10 11 12
Device(config-cmap)# exit

This example shows how to create a class map called class3, which matches all the incoming traffic with IP-precedence values of 5, 6, and 7: 

Device(config)# class-map class3
Device(config-cmap)# match ip precedence 5 6 7 
Device(config-cmap)# exit

This example shows how to delete the IP-precedence match criteria and to classify traffic using acl1: 

Device(config)# class-map class2
Device(config-cmap)# match ip precedence 5 6 7 
Device(config-cmap)# no match ip precedence
Device(config-cmap)# match access-group acl1
Device(config-cmap)# exit

This example shows how to specify a list of physical ports to which an interface-level class map in a hierarchical policy map applies: 

Device(config)# class-map match-any class4
Device(config-cmap)# match cos 4
Device(config-cmap)# exit

This example shows how to specify a range of physical ports to which an interface-level class map in a hierarchical policy map applies: 

Device(config)# class-map match-any class4
Device(config-cmap)# match cos 4
Device(config-cmap)# exit

You can verify your settings by entering the show class-map privileged EXEC command.

policy-map

To create or modify a policy map that can be attached to multiple physical ports or switch virtual interfaces (SVIs) and to enter policy-map configuration mode, use the policy-map command in global configuration mode. Use the no form of this command to delete an existing policy map and to return to global configuration mode.

policy-map policy-map-name

Syntax Description

policy-map-name

Name of the policy map.

Command Default

No policy maps are defined.

Command Modes

Modification

Cisco IOS XE Everest 16.5.1a

This command was introduced.

Usage Guidelines

After entering the policy-map command, you enter policy-map configuration mode, and these configuration commands are available:

  • class —Defines the classification match criteria for the specified class map.

  • description —Describes the policy map (up to 200 characters).

  • exit —Exits policy-map configuration mode and returns you to global configuration mode.

  • no —Removes a previously defined policy map.

  • sequence-interval —Enables sequence number capability.

To return to global configuration mode, use the exit command. To return to privileged EXEC mode, use the end command.

Before configuring policies for classes whose match criteria are defined in a class map, use the policy-map command to specify the name of the policy map to be created, added to, or modified. Entering the policy-map command also enables the policy-map configuration mode in which you can configure or modify the class policies for that policy map.

You can configure class policies in a policy map only if the classes have match criteria defined for them. To configure the match criteria for a class, use the class-map global configuration and match class-map configuration commands. You define packet classification on a physical-port basis.

Only one policy map per ingress port is supported. You can apply the same policy map to multiple physical ports.

You can apply a nonhierarchical policy maps to physical ports. A nonhierarchical policy map is the same as the port-based policy maps in the device.

A hierarchical policy map has two levels in the format of a parent-child policy. The parent policy cannot be modified but the child policy (port-child policy) can be modified to suit the QoS configuration.

In VLAN-based QoS, a service policy is applied to an SVI interface.


Note
Not all MQC QoS combinations are supported for wired ports. For information about these restrictions, see chapters "Restrictions for QoS on Wired Targets" in the QoS configuration guide.

Examples

This example shows how to create a policy map called policy1. When attached to the ingress port, it matches all the incoming traffic defined in class1, sets the IP DSCP to 10, and polices the traffic at an average rate of 1 Mb/s and bursts at 20 KB. Traffic less than the profile is sent. 

Device(config)# policy-map policy1
Device(config-pmap)# class class1
Device(config-pmap-c)# set dscp 10
Device(config-pmap-c)# police 1000000 20000 conform-action transmit
Device(config-pmap-c)# exit

This example show you how to configure hierarchical polices: 

Device# configure terminal
Device(config)# class-map c1
Device(config-cmap)# exit

Device(config)# class-map c2
Device(config-cmap)# exit

Device(config)# policy-map child
Device(config-pmap)# class c1

This example shows how to delete a policy map: 

Device(config)# no policy-map policymap2

You can verify your settings by entering the show policy-map privileged EXEC command.

priority

To assign priority to a class of traffic belonging to a policy map, use the priority command in policy-map class configuration mode. To remove a previously specified priority for a class, use the no form of this command.

priority [ Kbps [ burst -in-bytes] | level level-value [ Kbps [ burst -in-bytes] ] | percent percentage [ Kb/s [ burst -in-bytes] ] ]

no priority [ Kb/s [ burst -in-bytes] | level level value [ Kb/s [ burst -in-bytes] ] | percent percentage [ Kb/s [ burst -in-bytes] ] ]

Syntax Description

Kb/s

(Optional) Guaranteed allowed bandwidth, in kilobits per second (kbps), for the priority traffic. The amount of guaranteed bandwidth varies according to the interface and platform in use. Beyond the guaranteed bandwidth, the priority traffic will be dropped in the event of congestion to ensure that the nonpriority traffic is not starved. The value must be between 1 and 2,000,000 kbps.

burst -in-bytes

(Optional) Burst size in bytes. The burst size configures the network to accommodate temporary bursts of traffic. The default burst value, which is computed as 200 milliseconds of traffic at the configured bandwidth rate, is used when the burst argument is not specified. The range of the burst is from 32 to 2000000 bytes.

level level-value

(Optional) Assigns priority level. Available values for level-value are 1 and 2. Level 1 is a higher priority than Level 2. Level 1 reserves bandwidth and goes first, so latency is very low.

percent percentage

(Optional) Specifies the amount of guaranteed bandwidth to be specified by the percent of available bandwidth.

Command Default

No priority is set.

Command Modes

Policy-map class configuration (config-pmap-c)

Command History

Release Modification

Cisco IOS XE Everest 16.5.1a

This command was introduced.

Usage Guidelines

The bandwidth and priority commands cannot be used in the same class, within the same policy map. However, these commands can be used together in the same policy map.

When the policy map containing class policy configurations is attached to the interface to stipulate the service policy for that interface, available bandwidth is assessed. If a policy map cannot be attached to a particular interface because of insufficient interface bandwidth, the policy is removed from all interfaces to which it was successfully attached.

Examples

The following example shows how to configure the priority of the class in policy map policy1: 

Device(config)# class-map cm1
Device(config-cmap)#match precedence 2
Device(config-cmap)#exit

Device(config)#class-map cm2
Device(config-cmap)#match dscp 30
Device(config-cmap)#exit

Device(config)# policy-map policy1
Device(config-pmap)# class cm1
Device(config-pmap-c)# priority level 1
Device(config-pmap-c)# police 1m
Device(config-pmap-c-police)#exit
Device(config-pmap-c)#exit
Device(config-pmap)#exit

Device(config)#policy-map policy1
Device(config-pmap)#class cm2
Device(config-pmap-c)#priority level 2
Device(config-pmap-c)#police 1m

Usage Guidelines

Either the bandwidth , shape , or priority command must be used before using this command. For more information about these commands, see Cisco IOS Quality of Service Solutions Command Reference available on Cisco.com

The device allows you to allocate buffers to queues. If buffers are not allocated, then they are divided equally amongst all queues. You can use the queue-buffer ratio to divide it in a particular ratio. The buffers are soft buffers because Dynamic Threshold and Scaling (DTS) is active on all queues by default.

Examples

The following example sets the queue buffers ratio to 10 percent: 


Device(config)# policy-map policy_queuebuf01
Device(config-pmap)# class-map class_queuebuf01
Device(config-cmap)# exit
Device(config)# policy policy_queuebuf01
Device(config-pmap)# class class_queuebuf01
Device(config-pmap-c)# bandwidth percent 80
Device(config-pmap-c)# queue-buffers ratio 10
Device(config-pmap)# end

You can verify your settings by entering the show policy-map privileged EXEC command.

queue-limit

To specify or modify the maximum number of packets the queue can hold for a class policy configured in a policy map, use the queue-limit policy-map class configuration command. To remove the queue packet limit from a class, use the no form of this command.

queue-limit {queue-limit-size [packets] | cos cos-value | dscp dscp-value | exp {exp-value {maximum threshold [packets] | percent percentage -value} | values {exp-value percent percentage -value | percent | | percentage -value}} | percent percentage-of-packets | precedence {IP precedence value {maximum threshold [packets] | percent percentage -value} | values {precedence values percent percentage-value | percent | | percentage -value}}}

no queue-limit {queue-limit-size [packets] | cos cos-value | dscp dscp-value | exp {exp-value {maximum threshold [packets] | percent percentage -value} | values {exp-value percent percentage -value | percent | | percentage -value}} | percent percentage-of-packets | precedence {IP precedence value {maximum threshold [packets] | percent percentage -value} | values {precedence values percent percentage-value | percent | | percentage -value}}}

Syntax Description

queue-limit-size

This command was introduced.

The keywords exp and precedence are supported on Cisco Catalyst 9500 High Performance Series Switches

Usage Guidelines

Although visible in the command line help-strings, the packets unit of measure is not supported; use the percent unit of measure.


Note

This command is supported only on wired ports in the egress direction.

Weighted fair queuing (WFQ) creates a queue for every class for which a class map is defined. Packets satisfying the match criteria for a class accumulate in the queue reserved for the class until they are sent, which occurs when the queue is serviced by the fair queuing process. When the maximum packet threshold you defined for the class is reached, queuing of any further packets to the class queue causes tail drop.

You use queue limits to configure Weighted Tail Drop (WTD). WTD ensures the configuration of more than one threshold per queue. Each class of service is dropped at a different threshold value to provide for QoS differentiation.

You can configure the maximum queue thresholds for the different subclasses of traffic, that is, DSCP and CoS and configure the maximum queue thresholds for each subclass.

Examples

The following example configures a policy map called port-queue to contain policy for a class called dscp-1. The policy for this class is set so that the queue reserved for it has a maximum packet limit of 20 percent: 

Device(config)# policy-map policy11
Device(config-pmap)# class dscp-1
Device(config-pmap-c)# bandwidth percent 20
Device(config-pmap-c)# queue-limit dscp 1 percent 20

random-detect cos

To change the minimum and maximum packet thresholds for the Class of service (CoS) value, use the random-detect cos command in QoS policy-map class configuration mode. To return the minimum and maximum packet thresholds to the default for the CoS value, use the no form of this command.

random-detect cos cos-value percent min-threshold max-threshold

no random-detect cos cos-value percent min-threshold max-threshold

Syntax Description

cos-value

The CoS value, which is IEEE 802.1Q/ISL class of service/user priority value. The CoS value can be a number from 0 to 7.

percent

Specifies that the minimum and threshold values are in percentage.

min-threshold

This command was introduced.

Usage Guidelines

Use the random-detect dscp command in conjunction with the random-detect command in QoS policy-map class configuration mode.

The random-detect dscp command is available only if you specified the dscp-based argument when using the random-detect command in interface configuration mode.

Specifying the DSCP Value

The random-detect dscp command allows you to specify the DSCP value per traffic class. The DSCP value can be a number from 0 to 63, or it can be one of the following keywords: af11 , af12 , af13 , af21 , af22 , af23 , af31 , af32 , af33 , af41 , af42 , af43 , cs1 , cs2 , cs3 , cs4 , cs5 , cs7 , ef , or rsvp .

On a particular traffic class, eight DSCP values can be configured per traffic class. Overall, 29 values can be configured on a traffic class: 8 precedence values, 12 Assured Forwarding (AF) code points, 1 Expedited Forwarding code point, and 8 user-defined DSCP values.

Assured Forwarding Code Points

The AF code points provide a means for a domain to offer four different levels (four different AF classes) of forwarding assurances for IP packets received from other (such as customer) domains. Each one of the four AF classes is allocated a certain amount of forwarding services (buffer space and bandwidth).

Within each AF class, IP packets are marked with one of three possible drop precedence values (binary 2{010}, 4{100}, or 6{110}), which exist as the three lowest bits in the DSCP header. In congested network environments, the drop precedence value of the packet determines the importance of the packet within the AF class. Packets with higher drop precedence values are discarded before packets with lower drop precedence values.

The upper three bits of the DSCP value determine the AF class; the lower three values determine the drop probability.

Examples

The following example enables WRED to use the DSCP value 8. The minimum threshold for the DSCP value 8 is 20, the maximum threshold is 40, and the mark probability is 1/10.

To return the values to the default for the precedence, use the no form of this command.

random-detect precedence precedence percent min-threshold max-threshold

no random-detect precedence

Syntax Description

precedence

IP precedence number. The value range is from 0 to 7; see Table 1 in the “Usage Guidelines” section.

percent

Indicates that the threshold values are in percentage.

min-threshold

Minimum threshold in number of packets. The value range of this argument is from 1 to 512000000. When the average queue length reaches the minimum threshold, WRED randomly drops some packets with the specified IP precedence.

max-threshold

Maximum threshold in number of packets. The value range of this argument is from the value of the min-threshold argument to 512000000. When the average queue length exceeds the maximum threshold, WRED or dWRED drop all packets with the specified IP precedence.

Command Default

The default min-threshold value depends on the precedence. The min-threshold value for IP precedence 0 corresponds to half of the max-threshold value. The values for the remaining precedences fall between half the max-threshold value and the max-threshold value at evenly spaced intervals. See the table in the “Usage Guidelines” section of this command for a list of the default minimum threshold values for each IP precedence.

This command was introduced.

Usage Guidelines

WRED is a congestion avoidance mechanism that slows traffic by randomly dropping packets when congestion exists.

When you configure the random-detect command on an interface, packets are given preferential treatment based on the IP precedence of the packet. Use the random-detect precedence command to adjust the treatment for different precedences.

If you want WRED to ignore the precedence when determining which packets to drop, enter this command with the same parameters for each precedence. Remember to use appropriate values for the minimum and maximum thresholds.

Note that if you use the random-detect precedence command to adjust the treatment for different precedences within class policy, you must ensure that WRED is not configured for the interface to which you attach that service policy.


Note

Although the range of values for the min-threshold and max-threshold arguments is from 1 to 512000000, the actual values that you can specify depend on the type of random detect you are configuring. For example, the maximum threshold value cannot exceed the queue limit.

Examples

The following example shows the configuration to enable WRED on the interface and to specify parameters for the different IP precedences: 


interface FortyGigE1/0/1
 description 45Mbps to R1
 ip address 10.200.14.250 255.255.255.252

set qos-group {qos-group-value | dscp [table table-map-name] | precedence [table table-map-name]}

Syntax Description

cos

Sets the Layer 2 class of service (CoS) value or user priority of an outgoing packet. You can specify these values:

  • cos-value —CoS value from 0 to 7. You also can enter a mnemonic name for a commonly used value.

  • Specify a packet-marking category to set the CoS value of the packet. If you also configure a table map for mapping and converting packet-marking values, this establishes the "map from" packet-marking category. Packet-marking category keywords:

    • cos —Sets a value from the CoS value or user priority.

    • dscp —Sets a value from packet differentiated services code point (DSCP).

    • precedence —Sets a value from packet precedence.

    • qos-group —Sets a value from the QoS group.

  • (Optional)table table-map-name —Indicates that the values set in a specified table map are used to set the CoS value. Enter the name of the table map used to specify the CoS value. The table map name can be a maximum of 64 alphanumeric characters.

    If you specify a packet-marking category but do not specify the table map, the default action is to copy the value associated with the packet-marking category as the CoS value. For example, if you enter the set cos precedence command, the precedence (packet-marking category) value is copied and used as the CoS value.

dscp

Sets the differentiated services code point (DSCP) value to mark IP(v4) and IPv6 packets. You can specify these values:

  • cos-value —Number that sets the DSCP value. The range is from 0 to 63. You also can enter a mnemonic name for a commonly used value.

  • Specify a packet-marking category to set the DSCP value of the packet. If you also configure a table map for mapping and converting packet-marking values, this establishes the "map from" packet-marking category. Packet-marking category keywords:

    • cos —Sets a value from the CoS value or user priority.

    • dscp —Sets a value from packet differentiated services code point (DSCP).

    • precedence —Sets a value from packet precedence.

    • qos-group —Sets a value from the QoS group.

  • (Optional)table table-map-name —Indicates that the values set in a specified table map will be used to set the DSCP value. Enter the name of the table map used to specify the DSCP value. The table map name can be a maximum of 64 alphanumeric characters.

    If you specify a packet-marking category but do not specify the table map, the default action is to copy the value associated with the packet-marking category as the DSCP value. For example, if you enter the set dscp cos command, the CoS value (packet-marking category) is copied and used as the DSCP value.

ip

Sets IP values to the classified traffic. You can specify these values:

  • dscp —Specify an IP DSCP value from 0 to 63 or a packet marking category.

  • precedence —Specify a precedence-bit value in the IP header; valid values are from 0 to 7 or specify a packet marking category.

precedence

Sets the precedence value in the packet header. You can specify these values:

  • precedence-value — Sets the precedence bit in the packet header; valid values are from 0 to 7. You also can enter a mnemonic name for a commonly used value.

  • Specify a packet marking category to set the precedence value of the packet.

    • cos —Sets a value from the CoS or user priority.

    • dscp —Sets a value from packet differentiated services code point (DSCP).

    • precedence —Sets a value from packet precedence.

    • qos-group —Sets a value from the QoS group.

  • (Optional)table table-map-name —Indicates that the values set in a specified table map will be used to set the precedence value. Enter the name of the table map used to specify the precedence value. The table map name can be a maximum of 64 alphanumeric characters.

    If you specify a packet-marking category but do not specify the table map, the default action is to copy the value associated with the packet-marking category as the precedence value. For example, if you enter the set precedence cos command, the CoS value (packet-marking category) is copied and used as the precedence value.

qos-group

Assigns a QoS group identifier that can be used later to classify packets.

  • qos-group-value —Sets a QoS value to the classified traffic. The range is 0 to 31. You also can enter a mnemonic name for a commonly used value.

  • dscp —Sets the original DSCP field value of the packet as the QoS group value.

  • precedence —Sets the original precedence field value of the packet as the QoS group value.

  • (Optional)table table-map-name —Indicates that the values set in a specified table map will be used to set the DSCP or precedence value. Enter the name of the table map used to specify the value. The table map name can be a maximum of 64 alphanumeric characters.

    If you specify a packet-marking category (dscp or precedence ) but do not specify the table map, the default action is to copy the value associated with the packet-marking category as the QoS group value. For example, if you enter the set qos-group precedence command, the precedence value (packet-marking category) is copied and used as the QoS group value.

Command Default

No traffic classification is defined.

Usage Guidelines

For the set dscp dscp-value command, the set cos cos-value command, and the set ip precedence precedence-value command, you can enter a mnemonic name for a commonly used value. For example, you can enter the set dscp af11 command, which is the same as entering the set dscp 10 command. You can enter the set ip precedence critical command, which is the same as entering the set ip precedence 5 command. For a list of supported mnemonics, enter the set dscp ? or the set ip precedence ? command to see the command-line help strings.

When you configure the set dscp cos command, note the following: The CoS value is a 3-bit field, and the DSCP value is a 6-bit field. Only the three bits of the CoS field are used.

When you configure the set dscp qos-group command, note the following:

  • The valid range for the DSCP value is a number from 0 to 63. The valid value range for the QoS group is a number from 0 to 99.

  • If a QoS group value falls within both value ranges (for example, 44), the packet-marking value is copied and the packets is marked.

  • If QoS group value exceeds the DSCP range (for example, 77), the packet-marking value is not be copied and the packet is not marked. No action is taken.

The set qos-group command cannot be applied until you create a service policy in policy-map configuration mode and then attach the service policy to an interface or ATM virtual circuit (VC).

To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode, use the end command.

Examples

This example shows how to assign DSCP 10 to all FTP traffic without any policers: 


Device(config)# policy-map policy_ftp
Device(config-pmap)# class-map ftp_class
Device(config-cmap)# exit
Device(config)# policy policy_ftp
Device(config-pmap)# class ftp_class
Device(config-pmap-c)# set dscp 10
Device(config-pmap)# exit

You can verify your settings by entering the show policy-map privileged EXEC command.
